Project XMC: Flow Bench Testing Gains Over 80CFM!! | Holley Carburetor Mods | Removed Choke Tower

project XMC stage 1 flow numbers are in from @josephnowak and all I can say is WOW IMPRESSIVE!

   • Holley 600 Carburetor | Choke Horn De...  
be sure to watch this video to get the full flow testing and results!

and that was the very minimal amount of carburetor modification we could have done, just cut the choke tower off, radius the entry, knife edge the butterflies, and thin the throttle shafts.....that was it!

but now it is time for stage 2 to start..and it is going to put the X-tream in XMC. we are going to J&B weld the entire entrance of the carburetor and make our own! then we are going to hone out the bottom of the venturi bores to accept the larger 750cfm baseplate, and lastly we are going to replace the stock pressed in air bleeds with screw in....but not on the main body....on the Metering Block Itself!
